Multiple versions of autosave files
There is an addon now. You can find it here.

The Save on open option lets you go back to the start, while Save before close covers you for forgetting to save when opening another file or starting a new one, it doesn't get triggered before closing blender so that can still get you. While they do sound good, they can be a bit much if you just go quickly looking through a lot of blend files.

File copies are saved with a timestamp prefix in the name, so you can easily see how old any copy is or choose how far back you want to go.
